View Original PubMed Abstract ↓

Pulmonary tuberculosis (TB) remains a global health threat, with individual genetic determinants like Toll-like receptor 2 (TLR2) gene variations potentially modulating immune responses to Mycobacterium tuberculosis. This systematic review evaluates the role of TLR2 polymorphisms in influencing susceptibility to and clinical manifestations of pulmonary TB. Following PRISMA guidelines, a comprehensive search of PubMed, Scopus, and ScienceDirect was conducted through July 2024 for observational studies investigating TLR2 single-nucleotide polymorphisms (SNPs) and active TB. Risk of bias was assessed using the Newcastle-Ottawa Scale. Of 8878 identified articles, 32 studies met the inclusion criteria. The most frequently investigated variants, Arg753Gln (rs5743708), -196 to -174 del, and rs3804099, were consistently associated with increased TB susceptibility, particularly in Asian and African populations. Furthermore, specific polymorphisms correlated with greater disease severity, including cavitary lesions and aggressive clinical progression. In conclusion, TLR2 genetic polymorphisms significantly increase the risk of developing pulmonary TB and contribute to more severe clinical outcomes. These findings emphasize the potential of genetic profiling in enhancing TB control strategies and developing personalized diagnostic or therapeutic approaches.

Effectiveness and Safety of Acupuncture for Post-Stroke Neurogenic Bladder: A Systematic Review and Meta-Analysis.
Clinical Trial Synthesis 2026 Meta-Analysis published in Medicina (Kaunas, Lithuania) involving n = 727 participants; statistical significance reported at p = 0.001 (RR 1.23). Key conclusion: However, no definitive conclusions can be drawn regarding its clinical efficacy or safety due to the very low certainty of evidence, high methodological heterogeneity, and limited reporting of adverse events.
View Original PubMed Abstract ↓

Objective: This review is to systematically evaluate the clinical effectiveness and safety of acupuncture therapy for patients with post-stroke neurogenic bladder (PSNB). Methods: We included randomized controlled trials (RCTs) evaluating any type of acupuncture treatment for PSNB. Data extraction and quality assessment using Cochrane Risk of Bias 2.0 were performed. Meta-analysis was conducted for total effective rate (TER) and urodynamic parameters. Results: Ten RCTs involving 727 participants were included. Meta-analysis showed that acupuncture was associated with a reduction in residual urine volume (RUV), and increases in maximum cystometric capacity (MCC), and maximal urinary flow rate (Qmax). Acupuncture also showed a higher TER compared to control groups (RR = 1.23, 95% CI [1.15, 1.33], p < 0.001). However, wide 95% prediction intervals for urodynamic parameters indicated substantial uncertainty for future clinical applications. Adverse events were mild and infrequent, but only partly reported in two studies among included trials. Conclusions: Acupuncture as an adjunctive therapy suggests potential trends for improving clinical efficacy and urodynamic parameters in PSNB patients. However, no definitive conclusions can be drawn regarding its clinical efficacy or safety due to the very low certainty of evidence, high methodological heterogeneity, and limited reporting of adverse events. Therefore, these results must be interpreted with extreme caution. Further high-quality, large-scale randomized controlled trials with standardized protocols are essential to establish robust evidence regarding its clinical effectiveness and safety.

View Original PubMed Abstract ↓

Background and Objectives: Rituximab, a monoclonal antibody targeting CD20+ B-cells, is used in autoimmune diseases and B-cell malignancies. Recently, rituximab has been used as an induction agent in kidney transplantation. Our study evaluates the efficacy of rituximab induction on biopsy-proven acute rejection (BPAR), patient survival, and graft survival in ABO-compatible patients. Materials and Methods: A systematic literature search was performed across five databases, following PRISMA guidelines, and the protocol was registered in PROSPERO (CRD42024603984). The inclusion criteria consisted of randomized controlled trials (RCTs), exploring the impact of rituximab induction on eligible kidney transplant recipients with BPAR, graft, and patient survival as the primary outcomes. Risk ratios (RR) with 95% confidence intervals (CI) were estimated by the random-effects model. The risk of bias was assessed via the Cochrane ROB-2 tool across five domains. Results: From an initial 859 potentially relevant studies, three RCTs, including 454 patients, met the inclusion criteria. At 6 months, rituximab was associated with a non-significant reduction in the risk of BPAR (RR 0.76; 95% CI, 0.50-1.15; I2 = 0%). Similarly, patient survival remained unchanged at 6 months (RR 1.01; 95% CI, 0.98-1.04; I2 = 0%). Due to significant heterogeneity, long-term outcomes were assessed using narrative synthesis, which revealed no additional benefit for rituximab in terms of graft or patient survival. Furthermore, potential safety concerns-especially in terms of infection risk-were noted. The certainty of this evidence was low, due to clinical heterogeneity in the included studies causing very serious indirectness. Conclusions: Induction with rituximab provides no significant benefit over standard regimens. Thus, its routine use in ABO-compatible renal transplants may not be justified. The available evidence is of low certainty. Further trials are needed before drawing a firm conclusion and to determine the best dosage, timing, and combinations.

View Original PubMed Abstract ↓

BACKGROUND: Postprandial triglyceride (TG) metabolism represents a dynamic dimension of lipid physiology that complements conventional fasting lipid assessment. Although low-density lipoprotein cholesterol (LDL-C) remains the primary therapeutic target in cardiovascular prevention, residual cardiovascular risk persists in many individuals despite apparently adequate fasting lipid control. Because most individuals spend the majority of their waking hours in a fed state, postprandial TG responses may provide clinically relevant insight into metabolic flexibility, dietary exposure, and the efficiency of TG-rich lipoprotein clearance. METHODS: This narrative review was conducted using a literature search guided by predefined themes, keywords, and databases, without following a formal systematic review protocol. Randomized controlled trials, observational studies, meta-analyses, and major reviews addressing postprandial lipid metabolism, dietary determinants, and cardiometabolic risk were included, with priority given to human studies. RESULTS: Postprandial TG responses are strongly influenced by dietary composition, eating patterns, and metabolic health. Individuals with insulin resistance, type 2 diabetes, obesity, and metabolic-associated steatotic liver disease (MASLD) frequently demonstrate exaggerated or prolonged postprandial lipemia even when fasting TG concentrations appear acceptable. While circulating TGs serve as practical clinical markers of postprandial lipid handling, cholesterol-enriched remnant lipoproteins more closely reflect atherogenic burden. Nutritional interventions, weight management, and physical activity consistently improve postprandial TG dynamics, whereas pharmacologic therapy provides additional benefit in selected high-risk patients. Non-fasting TG measurements may provide additional insight into postprandial lipid metabolism and residual cardiovascular risk, although standardized protocols and validated clinical thresholds remain to be established. CONCLUSIONS: Postprandial TG metabolism provides clinically meaningful information beyond fasting lipid measurements and represents a useful adjunct for refining residual cardiovascular ris

Genetic Ancestry and Population Structure Across Ecuador.
Clinical Trial Synthesis 2026 Meta-Analysis published in Genes. Key conclusion: Conclusions: Ecuadorian populations share a broad three-way admixture framework, but with marked internal heterogeneity across regions and population groups.
View Original PubMed Abstract ↓

Background: Ecuador is a genetically diverse population setting shaped by long-term interactions among Native American, European, and African populations across distinct ecological regions. Although multiple studies have examined ancestry patterns in Ecuadorian populations, the available evidence remains fragmented and methodologically heterogeneous. Objective: To systematically identify, critically appraise, and synthesize published studies on genetic ancestry and population structure in Ecuador. Methods: A systematic review was conducted in accordance with PRISMA 2020. Searches were performed in PubMed/MEDLINE, Scopus, Web of Science Core Collection, SciELO, and Google Scholar through 31 January 2026. Eligible studies reported extractable ancestry-related data from Ecuadorian populations using autosomal, mitochondrial DNA, Y-chromosomal, or other ancestry-relevant genetic markers. Methodological quality was assessed using an adapted Joanna Briggs Institute framework. Owing to substantial heterogeneity across marker systems, sampling strategies, and ancestry inference methods, findings were synthesized qualitatively rather than by meta-analysis. Results: Of 1243 records identified, 12 studies met the inclusion criteria. Across marker systems, the evidence consistently supported a three-way admixture framework involving Native American, European, and African ancestry components, together with substantial regional and population-specific heterogeneity. Autosomal studies generally showed higher Native American ancestry in Highland and Native American populations, whereas African ancestry was more prominent in Afro-Ecuadorian and some Coastal populations. Uniparental markers further supported persistent sex-biased admixture, with predominant Native American maternal lineages and comparatively greater European or African paternal contributions depending on region and population history. Conclusions: Ecuadorian populations share a broad three-way admixture framework, but with marked internal heterogeneity across regions and population groups. These findings highlight the importance of geographic and demographic context in ancestry interpretation and the need for larg

Life expectancy (LE) varies widely across Organization of Islamic Cooperation (OIC) countries, reflecting differences in economic, social, environmental, and health-system conditions. This review aimed to synthesize quantitative evidence on determinants of LE at birth in OIC member countries. The study was conducted in accordance with the PRISMA guidelines, and a systematic search of electronic databases was performed up to September 2025. After screening 5312 records and assessing full texts, studies were appraised using the Joanna Briggs Institute checklists, with an inclusion threshold of ≥80%. A total of 54 studies, mainly ecological, time-series, and panel analyses using national-level data, were included. Higher gross domestic product per capita, education, employment, and health expenditure were consistently associated with longer LE. In contrast, poverty, income inequality, air pollution, and carbon dioxide emissions were associated with shorter LE. Clear differences were observed across World Bank income groups, with LE being lowest in low-income OIC countries and highest in high-income Gulf Cooperation Council states, where gains were driven more by health-system resources than by income growth. Improving LE in OIC countries requires integrated economic, social, environmental, and health-system policies.

OBJECTIVE: This review aimed to synthesize evidence on the design characteristics, implementation considerations, and operational challenges of mobile cancer screening units. METHODS: A PRISMA-guided review was conducted. Data extracted included screening type, target population, program characteristics, mobile unit features, and reported implementation barriers. Study quality was assessed using the Mixed Methods Appraisal Tool (MMAT). RESULTS: Sixty-four articles published across 13 countries met the inclusion criteria. Most interventions focused on breast cancer screening (n = 37), followed by lung (n = 11), cervical (n = 6), colorectal, skin, prostate, and multi-cancer screening programs. MSUs were most frequently deployed in urban areas (21 urban/18 rural/17 both). Several comparative studies (fixed programs vs. MSUs) reported higher screening uptake in mobile programs, although findings varied substantially by setting, population, and study design. However, adherence and clinical outcomes varied, often reflecting baseline socioeconomic differences in the populations served. Common implementation barriers included follow-up coordination challenges, program costs, equipment and space limitations, and gaps in referral and reimbursement systems. CONCLUSIONS: These findings highlight the potential of mobile screening units as public health strategies to expand access to cancer screening while underscoring the need for stronger implementation frameworks and long-term evaluation of program outcomes.

Mechanistic Insights into Multiherb Formulations for Antibiotic-Associated Diarrhea: A Systematic Review of Preclinical Studies on Microbiome-Host Interactions.
Clinical Trial Synthesis 2026 Systematic Review published in International journal of molecular sciences. Key conclusion: Botanical interventions may facilitate endogenous microbiome recovery by reinforcing mucosal integrity and reducing environmental resistance.
View Original PubMed Abstract ↓

Antibiotic-associated diarrhea (AAD) is primarily driven by disruption of the gut microbiota accompanied by intestinal mucosal injury. Although multiherb formulations are widely used in East Asian medicine, their collective ecological effects and integrated microbiome-host mechanisms have not been systematically synthesized. This systematic review included 17 preclinical studies that investigated multiherbal formulations in AAD models. Given the substantial heterogeneity in the formulation composition, experimental design, and analytical platforms, a descriptive synthesis was performed. The included formulations were categorized into four clusters based on their shared herbal composition: Qiwei Baizhu San (QWBZP), Lizhong Tang (LZT), Gegen Qinlian Tang (GQT), and other supportive multiherbal formulations. The cluster-based synthesis revealed distinct convergent therapeutic strategies. The QWBZP and LZT clusters primarily supported the restoration of host metabolic and digestive functions, whereas the GQT cluster exhibited potent pathogen control effects with the suppression of opportunistic taxa. Across all clusters, a convergent microbiome-host response emerged, characterized by enrichment of commensal bacteria (e.g., Lactobacillus), upregulation of tight junction proteins (e.g., ZO-1, occludin), and attenuation of pro-inflammatory mediators (e.g., TNF-α, myeloperoxidase). Multiherb formulations in AAD models not only act as microbial modulators but also function as host-directed modulators that stabilize the intestinal homeostatic niche. Botanical interventions may facilitate endogenous microbiome recovery by reinforcing mucosal integrity and reducing environmental resistance. This ecological framework provides a rationale for future translational studies evaluating integrated herbal-probiotic strategies and precise microbiome management for patients with AAD, while further clinical validation is warranted.

View Original PubMed Abstract ↓

The disproportionately severe disease course of diabetic patients with SARS-CoV-2 infection was repeatedly observed by clinicians during the COVID-19 pandemic. The overlap between metabolic impairment, viral pathophysiology, and chronic inflammation created a pattern that urged deeper examination. The aim of this paper was to review and synthesize evidence regarding the interaction between diabetes mellitus and COVID-19. We synthesized evidence across mechanistic pathways (immune dysregulation, chronic inflammation, ACE2/DPP-4-related signaling, endothelial dysfunction, and pancreatic involvement) and key clinical outcomes (severity, intensive care unit (ICU) admission, mortality, dysglycaemia/new-onset diabetes, and DKA). This systematic search was conducted in PubMed, Clinical Key, and Google Scholar. The eligibility criteria included papers on adults (≥18 years) with pre-existing diabetes mellitus (type 1 or type 2) or newly diagnosed diabetes/hyperglycemia and confirmed SARS-CoV-2 infection, published between January 2020 and October 2025, in English language. The PRISMA guidelines were used for data extraction. We identified 412 articles, out of which only 30 met all the inclusion criteria. Diabetes was consistently evoked as a major risk factor for severe COVID-19, being associated with higher susceptibility to pneumonia, respiratory failure, ICU admission, and mortality. The explanation lies in the impaired immune system, endothelial dysfunction, and metabolic repercussions imposed by hyperglycemia. Several antidiabetic drugs appeared protective in multiple cohorts. In conclusion, the accumulated evidence underscores the tight interplay between metabolic disease and COVID-19. Essentially, the clinical management of these patients would be a thoughtful selection of antidiabetic therapy and close metabolic monitoring.

View Original PubMed Abstract ↓

Acute coronary syndrome patients undergoing percutaneous coronary intervention remain at high risk for major adverse cardiovascular events (MACE: cardiovascular mortality, non-fatal myocardial infarction, and stroke). Inflammatory-oxidative stress biomarkers are potential prognostic tools; however, the influence of sampling timing-pre-procedural versus post-procedural-remains unclear. This meta-analysis evaluated six biomarkers: sST2, GDF-15, OPG, sLOX-1, H-FABP, and Galectin-3. Pooled Hazard Ratios (HRs) for time-to-event outcomes and Standardized Mean Differences (SMDs) between event and non-event groups were synthesized using random-effects models involving 40 studies (18,933 patients). Elevated pre-procedural levels of sST2 (HR = 3.32, p < 0.0001), GDF-15 (HR = 3.00, p < 0.0001), sLOX-1 (HR = 2.61, p = 0.0023), and OPG (HR = 1.79, p = 0.0206) significantly predicted MACE. Notably, pre-PCI sST2 strongly predicted heart failure hospitalization (HR = 6.30, p < 0.0001). Additionally, pre-PCI H-FABP demonstrated a moderate significant effect on adverse outcomes (SMD = 0.67, p < 0.0001). While pre-PCI Galectin-3 was not significant, its post-procedural levels showed a large significant effect (SMD = 1.15, p < 0.0001). In conclusion, inflammatory and oxidative stress biomarkers, particularly sST2 and GDF-15, demonstrate consistent associations with adverse outcomes in ACS patients undergoing PCI, offering more reliable baseline risk stratification than post-procedural measurements.
